BOTTLE FILLING AND cAPPmG MACHINE.

Specification of Letters Patent.

' Patented June 29, 1969.

Application filed February '20, 1907. Serial No. 858,474.

Be it known that I, Gnone KIRKEGAARD, a citizen of the United States, and a resident of the city of New York, in the county of New York, State of New York, United States of America, have invented certain new and useful Improvements in Bottle Filling and Capping Machines, of which the following is a specification.

My invention relates to a bottle filling and capping machine and its object is to provide a simple and sellicicnt apparatus for filling bottles under pressure and applying caps thereto.

Iwill describe my invention in the following specification and point out the novel features thereof in claims.

Referring to the drawings Figure 1 is a side elevation of a bottlecapping machine made according to my invention, certain of the parts being broken away and shown in section.- Fig. 2 is a sectional side elevation of an improved bottle filling and cap applying head. Fig. 3 is a side elevation, partly in section, of the parts shown in Fig. 2, this figure showing the parts in different relative positions. Fig. 4 is a sectional plan view, the section being taken through the line 4-4 of Fig. 2. Fig. 5 is a sectional plan view of a valve mechanism, the section being taken through the line 5 of Fig. 2. Fig. 6 is a sectional plan view showingthe operating spindle and compression shaft, the section being taken through the line 6-6 of Fig. 2. Fig. 7 is a perspective view of a bottle cap which 'Ihave invented and which may be used to advantage with this apparatus.

Likecharacters of reference deslgnate correspondingparts.in all of the figures.

10 designates a base or framework upon which the various parts of my apparatus are hand screws 13, 13.

' mounted.

11, 11 are vertica tandards connectcd with this framework and arranged to support certain of the parts. 12'designates a head or supporting carriage slidably mounted upon these standards and arranged to be held at a desired height by means of At a point 14 on the supporting-carriage is pivoted a hand lever 15. 16 designates a slot in this hand lever. .A pin 17 is arranged to pass through the slot 16.

-ward from the spindle by means of a compression spring 24. A pin 25 passes through this compression shaft 23 and through a slot 26 in the side of the spindle. This pin prevents the compression shaft from being pushed down out of the spindle but allows of a certain vertical movement of the compression shaft within the spindle.

27, 27 designate two packing rings about the compression shaft to revent the upward flow of liquid from the illing chamber into the spindle 20. The lower end of the spindle is constructed to form a piston 28 which is provided with a packing ring .29.

3O designates a split cam ring which is arranged to be held within the lower end of the spindle 20 by means of a shoulder 31 which may the spindle.

32, 32 designate -locking-pawls or lingers which are pivoted. to thelower end of the compression shaft and pressed outward by means of springs 33. The lower end of the compression shaft may be provided with a recess and a magnet 34 placed therein.

40 designates a casing which is constructed to form a cylindrical filling chamber 11, the upper ortion of this casing extending over the en arged lower end 'of the spindle 20 and a spring 42 being interposed between the upper surface of the casing and'tho ortion 19 of the supporting-carriagc. The ower edge the casing 40 is provided with a sharp annular rim-43 which is adapted to engage with a package which I will describe later. Associated with this casing 40 is a valve 44 which is arranged to control various ports.

50 designates a packing collar which is attached at 51 to a portion of the base of frame 10, and 52 designates a similar packing-collar which is movablysupported 110 be secured onto the bottom of the top of the bottle 60.

' in the frame 10.

until the lower edge 43 ol the casing fits 'shal'tbefore the casing has been lowered through passage 81 by opening valve 44.

pressed iirmly against the mouth ol' the upon a slide 53 which slide is also supported This slide may be actuated by means oi a bell-crank'leve'r 54 which is pivoted at 55 and which is normally pressed to move the slide 53 outward by means pl' a spring 56, but-which may be 'IIIOVOd in the opposite direction by means of a vertical connecting-rod 57 which is connected with a treadle 58. p

A bottle 60 may be placed upon a bottlesupport 6], which is a part of the base or frame 10, with a portion of its neck against the packing-collar 50. \Yhen the trcadle 58 is repressed. the slidable pacl-;ing-collar 52 will be moved inward against the neck of the bottle 'so that the two packing-collars will together surround the neck 01 the bottle tightly. These packing-collars are preferably made of rubber or other resilient material. Another bottle 64 may be placed upon another bottle-support 65- upon the base or frame, after which the supportingcarriage '12 with its connected parts may be lowered upon the vertical standards 11, 11

into circular grooves 59 which are provided in the packing-collars 50 and 52. The casing and the packing-collars will thus form a filling chamber about the mouth of the bottle.

designates a bottle cap which I have invented and which comprises a flat disk 71 having a depending annular flange 72 and depending lugs or fingers 7 One of these caps may be placed upon the lower end of the compression shalt 23 and will be held thereon by the magnet 84. The cap should be placed upon the end of the compression into contact with the packing-collars.

8O designates a pipe from a suitable source of fluid supply, such, for example, as carbonated. fluid under pressure, which may be connected with the lilling chamber 41 This will cause the iilling chamber and the bottle to be iilled under pressure. The spindle 20 may then. be lowered by mcans of lever 15 and the compression shal't will move with the latter until the cap 70.nrccts This will arrcst the movement of the coniprcssion shalt 33. lhese caps are generally provided' with a packing material such as corl; and the spring 24 will cause this packing to be combottlc. A further movement ol-thc spindle 20 will cause the forming ring 30 to be moved down over the locking lingers 3?, 32 and cause the latter to be pressed inward. These fingers are arranged to be opposite the depending lugs 73, 7-; on the bottle cap and will cause the latter to be pushed in and under the annular rim or head (33 upon the bottle 60. In the foregoing action the 1 packing blocks are separated from the filling head. it may be seen that during this portion oi the operation the pressure in the bottle may be increased by snnplyclosing the passage 81 by the valve 44.

J0 designates an outlet passage in which is a safety valve 91 which will prevent the pressure in the bottle becoming too great.

8'2 designates a pipe from a second source of fluid suppl -J which arranged to be coni'iccted through the aivc 44 with the receiving chamber 8 when said valve is in its closed position. This receiving chamber is provided with a regulating screw 84 which may be adjusted to measure the amount of fluid which said chamber can receive. The lower portion of the valve 44 is provided with a port 85 hich is arranged to open a passage 86 when the passage Si is opened to the filling chamber 41; at the same time the passage 87 from the supply pipe 82 into the receiving chamber is closed and an air-vent 88 is opened into the top of this receivi'ng chamber. T" us it may be seen that any liquid which may have been introduced into the receiving chamber 83 may flow through the passage 86 into the bottle (34. which is directly under it. This arrange nicnt is utilized for filling a syrup of a certain measured quantity into the bottle 64 while bottle (30 is being charged under pressure by the apparatus which I have described. While the valve 44 is turned to close passage Si into the filling chamber 41 the passage 87 is opcned into the receiving chamber 83 and the amount of liquid which will llow into th s chamber is dcpcndent upon the position oi the rc' nlating screw 84.

YJ'hcn the bottle (5i) has been filled and sealed as above described the lever 15 may be reloascd and the spring 22 will cause the spindle 2i) and its connected parts to be raised. The carriage 12 may then be raised up above the packing-collars and the spring so allowed to move he. packing collar 52 away from the bottle. The tilled and sealed bottle G0 may then be removed, the bottle 64 put in its place, and anew bottle put in place of the bottle64 which has just been charged with a measuredsupply ol syrup I have described a portion of this appa: ratus as constructed for use in conjunction with a. specific l'orin of bottle cap which I have invented, but it" may, of course, be applied to other forms of bottle caps if desired.
